* Print symbols as symbols.Bernhard Schommer2018-03-081-0/+9
| | | | | | This allows us to replacing them by their address in valex and additionally checking them. Bug 22438
* Improve and simplify error messages.Bernhard Schommer2018-03-071-2/+6
| | | | | | | | The checks on the argument and format arguments are now performed during C2C translation by calling the validate_ais_annotations function and result in an error instead of a warning in the backend to be more consistent with the rest of the builtin functions.
* Reactivated and improved ais annotations.Bernhard Schommer2018-03-061-0/+31
The ais annotations are now handled in a separate file shared between all architectures. Also two different variants of replacements are supported, %e which expands to ais expressions and %l which also expands to an ais expression but is guaranted to be usable as l-value in the ais annotation. Otherwise the new warning is Wrong_is_parameter is generated. Also an error message is generated if floating point variables are used in ais annotations since a3 does not support them at the moment. Additionally an error message is generated for plain volatile variables used, since they will enforce a volatile load and result in the value being passed to the annotation instead of the address as other global variables.
